Series 1950A $10 Federal Reserve Note issued by the Federal Reserve Bank of Cleveland (indicated by the D prefix in the serial number and the corresponding "D" district code)..
Uncirculated Condition (Pristine): If the bill looks brand new with crisp paper, sharp corners, and no folds, .Highly graded uncirculated examples from the Cleveland district can fetch significantly higher premiums at auction or specialized retail
The "D" Designation: The letter D at the start of your serial number (D16371980B) links it directly to the 4th Federal Reserve District in Cleveland, Ohio.
No "In God We Trust": You might notice that your bill is missing the motto "In God We Trust" on the back. This is completely normal for the 1950 series; the motto wasn't added to $10 bills until later series.
Block Lettering: The serial number starts with "D" and ends with "B", which denotes the specific printing block. It is a standard production run (not a rare "star" replacement note).
